On the very last day of shooting [of The Last King of Scotlang], I remember wanting to get the [Idi Amin] character out of me right away, as much as I could. You literally take a bath to wash him off you. Luckily, I went into another part not so long afterwards, so I was kind of able to push it away a little bit. But speech patterns, and little sounds, particularly colloquial things, like the way you ask questions or might respond, were sticking with me, probably because I'd worked so hard to make it a part of my everyday way of expressing myself.

It is possible for a kid from east Texas, raised in south central LA and Carson, who believes in his dreams, commits himself to them with his heart, to touch them and to have them happen.

I do look at that thematic of healing of humanity.

I hope that audiences respond really positively. I think it's a very intense, entertaining film [The Last King of Scotland], because you're brought in on a fun ride, and slowly you fall into it as James [actor James McAvoy's character, Dr. Nicholas Garrigan] does. Nicholas is like the audience. I think it's a good ride for people. And you learn something, as well.

I think the biggest thing that motivates me when I'm choosing a part is a role that will help me continue to grow as a person and as an artist, and a role that will deepen my understanding of humanity, and my connection to it.

I can play a man who's despicable. But I'll still look inside him to find a point of connection. If I can find that kernel, audiences will relate to me.

Filming in Africa touched something really deep inside of me, really. It changed my matrix, my insides. My blood even feels kinda different. I don't know how to describe it. It's really kind of Eucharistic. I feel like I ate the place and now it's part of my system, part of my being. I'm not claiming that now I know what it's like to be African, but that now I have a deeper understanding of myself.
